madshi, just out of curiosity - do you use asynchronous I/O (ie. overlapped I/O) when reading and writing streams? I can easily saturate RAID0'd hard drives if I have 3 pending I/O requests going at the same time, using 32 megabyte buffers each request. Going from 50 MB/sec to 160 MB/sec is amazing!

May be a stupid question, but reading from bluray folder from hard disk is still supported? Cause I get "Error reading file ".\BDMV\STREAM\xxxxx.m2ts" with latest versions, but for example v3.01 works good

No, but I'm reading/writing in different threads, at least when multiple tracks are demuxed.

How many MBs does the current eac3to build do when doing simple demuxing (no audio transcoding)?

Should still work, and it seems to work for me. From which folder did you call eac3to and which command line did you use?

madshi, I actually haven't done any tests with recent builds of eac3to - sorry! I'll get around to it, one day... I do recall eac3to 2.xx was fairly decent for speeds.

For reference, I have 2 Samsung 1 TB Spinpoint F1 drives in a RAID0 configuration on a motherboard with Intel ICH8 SATA controller. File copies with Windows Explorer is dreadfully slow - 50 MB/sec, so it is pretty clear Windows XP doesn't do multithreaded or asynchronous I/O.
But Teracopy, which does asynchronous I/O, is roughly twice as fast.

"A lot of effort" is a relative term. It would be possible and doable, but it would cost some time, and I still have so many other things on my to do list. However, I could use some very limited cutting functionality myself for cleaning up the beginning of self-recorded broadcasts. So it might come sooner or later, but not too soon...

I have tried different Nero 7 versions (rebooting and using General-CleanTool after each uninstall)

7.2.7.0
7.5.1.1
7.5.9.0
7.7.5.1a
7.8.5.0
7.9.6.0
7.11.10.0

and eac3to always response with "Nero Audio Decoder (Nero 7) is not working correctly"

Special test - I choose Nero Audio Decoder as preffered in MPC and ...
if I am using mpc.exe to open MKV file with AC3 and MP3 track - only MP3 decoded by Nero Audio Decoder
if I rename mpc.exe to recode.exe and open the same file, then both type of tracks is decoded by Nero

And the most interesting thing, some time ago I have 7.11.10.0 installed and it was working for some time (eac3to), and then later it stopped working like this (renaming eac3to.exe to recode.exe don't help).
